OpenAI’s $6.6 Billion Share Sale Boosts Valuation to $500 B, Marking Largest Private‑Company Valuation
OpenAI sold $6.6 billion worth of shares held by current and former employees, a transaction that lifted its valuation to $500 billion, the highest ever for a privately held firm. The sale, which involved investors such as SoftBank, Dragoneer Investment Group, Thrive Capital, MGX and T. Rowe Price, was not a traditional funding round because the proceeds went directly to shareholders. The move comes amid heightened competition with Meta’s AI lab, recent large‑scale funding rounds, and strategic partnerships with Oracle, Nvidia and Microsoft, while the company continues to roll out new products like the Sora 2 video model.
